An example involves identifying a first artifact in an image on a display, the first artifact caused by a first subpixel of a first pixel, determining a type of the first artifact based on a location of the first artifact relative to content of the image, and correcting the first artifact to remove the appearance of the first artifact from the display based on the type of the first artifact.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An apparatus comprising: an artifact identifier to identify artifacts in an image presented on the display, the artifacts caused by artifact pixels, wherein the artifact identifier is to: identify potential artifact pixels corresponding to the artifacts; determine that intensities of the potential artifact pixels satisfies a threshold; and identify the potential artifact pixels as artifacts when the potential artifact pixels are in a dark neighborhood of the image the apparatus further comprising; an artifact classifier to classify the artifacts in the image as singlet artifacts, doublet artifacts, or triplet artifacts based on locations of the artifact pixels; and an artifact corrector to correct the artifacts to remove the artifacts from the display based on whether the artifacts are singlet artifacts, doublet artifacts, or triplet artifacts.
The system identifies and corrects visual artifacts on a display caused by individual pixels (artifact pixels). It first locates potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. Then, the system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other. Finally, it corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
2. The apparatus of claim 1 , wherein the artifact classifier classifies the artifacts as singlet artifacts when the artifacts are not diagonally adjacent other artifacts.
Building on the artifact correction system that identifies and corrects visual artifacts on a display, the system classifies an artifact as a "singlet" when the artifact pixel is not diagonally adjacent to any other identified artifact pixels. The system identifies potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. The system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
3. The apparatus of claim 1 , wherein the artifact classifier classifies the artifacts as doublet artifacts when the artifacts are diagonally adjacent to one other artifact.
Expanding on the artifact correction system that identifies and corrects visual artifacts on a display, the system classifies an artifact as a "doublet" when the artifact pixel is diagonally adjacent to exactly one other identified artifact pixel. The system identifies potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. The system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
4. The apparatus of claim 1 , wherein the artifact classifier classifies the artifacts as triplet artifacts when the artifacts are diagonally adjacent to two other artifacts.
Extending the artifact correction system that identifies and corrects visual artifacts on a display, the system classifies an artifact as a "triplet" when the artifact pixel is diagonally adjacent to two other identified artifact pixels. The system identifies potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. The system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
5. The apparatus of claim 1 , wherein the artifact classifier classifies the artifacts as doublet artifacts when the location of the artifacts are less than a threshold distance from one other artifact.
Within the artifact correction system for displays, which identifies and corrects visual artifacts, the system classifies artifacts as "doublets" if the distance between an artifact pixel and another artifact pixel is below a specific threshold. The system identifies potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. The system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
6. The apparatus of claim 1 , wherein the artifact classifier classifies the artifacts as triplet artifacts when: the location of a first artifact is less than a threshold distance from a second artifact, and the location of the first artifact is less than a threshold distance from a third artifact.
As part of the artifact correction system for displays, which identifies and corrects visual artifacts, the system classifies an artifact as a "triplet" if one artifact pixel is close to two other artifact pixels. Specifically, the distance between the first artifact and the second artifact, and the distance between the first artifact and the third artifact, must both be less than a defined threshold. The system identifies potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. The system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
7. The apparatus of claim 1 , wherein the artifact corrector to correct the artifacts to remove the artifacts from the display comprises: the artifact corrector to adjust an intensity of at least one pixel of the image.
In the artifact correction system that identifies and corrects visual artifacts on a display, the artifact correction mechanism operates by adjusting the brightness (intensity) of at least one pixel in the image. The system first locates potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. Then, the system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
8. The apparatus of claim 1 , wherein the artifact identifier is to identify artifacts in the image presented on the display based on intensities of subpixel components of pixels of the image.
As part of the artifact correction system which identifies and corrects visual artifacts on a display, the artifact identification process is based on the brightness (intensities) of the red, green, and blue (subpixel) components of the individual pixels in the image. The system identifies potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. Then, the system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
9. The apparatus of claim 1 , wherein the artifact identifier is to identify artifacts in the image presented on the display based on second derivative gradient. vectors of the image, the vectors comprising a mapping of spatial dimensions of the image to color dimensions of the image.
In the artifact correction system which identifies and corrects visual artifacts on a display, the artifact detection mechanism uses second derivative gradient vectors. These vectors map the spatial dimensions of the image (x, y coordinates) to the color dimensions (e.g., red, green, blue). By analyzing these vectors, the system can identify artifacts. The system identifies potential artifact pixels and checks if their brightness (intensity) exceeds a certain level. If the pixel is in a dark area of the image, it's marked as an artifact. Then, the system categorizes these artifacts as "singlets," "doublets," or "triplets" based on how close the artifact pixels are to each other, and corrects the appearance of these artifacts to remove them from the display, using different correction methods depending on whether they are singlets, doublets, or triplets.
